Applied to Tegra's for-3.7/common-clk branch. I re-tested that branch,
and the final re-merge of Tegra's for-next.
A nice side-effect of this, is that you can disable CONFIG_CPU_FREQ, and
still boot (since the CPU clock isn't turned off, since smp_twd is
clk_get()d which takes a reference to the CPU clock).
